ABSTRACT:
An air cleaner for miniature internal combustion engines to be used on model boats, airplanes, and the like, which is comprised of a tubular elastic boot and a removable filter unit. One end of the tubular elastic boot is stretched over and sealingly attached to the air inlet of the engine. Into the other end of the elastic boot member is inserted the filter unit so that all the air entering the engine must pass through the filter. The filter unit is comprised of a porous open cell foam medium which is supported on a peripheral flange to sealingly engage the elastic boot member.
